I have to say I was somewhat skeptical that this was a legit. offer because the price was so incredibly low. Well I bought it, and it works fine, and the purchase shows up on my official Microsoft account so if there is some issue in the future (like a get a new PC) I am safely registered. I am ALL IN on this company their support is OUTSTANDING! Do note that you have 30 days to install the product, this is not something to buy and put on the shelf for a rainy day! Jim
